DGR-019: Lock alpha and beta performance contracts

Status / triage: completed; passes: true
Execution mode: HITL
Milestone: M0
Dependencies: DGR-017
Blocks (derived): DGR-020, DGR-044, DGR-054
Labels: area:performance, type:contract, priority:p0, gate:hitl, ready-for-human
Evidence class: release
Hardware: required
Model: generic+deepseek-v4
Upstream: no

Objective / description

Fresh Ralph session: read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md, source issue .scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md, and evidence READMEs for dependencies (DGR-017) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Freeze useful speed, correctness, memory-fit, and stop/go thresholds before implementation results are visible.

Acceptance criteria

Define controlled safetensors, whole-model GGUF, dense distributed GGUF, and V4 Flash distributed lanes with fixed prompts, context/output lengths, sampling, concurrency, hardware, and metrics.
Alpha requires correctness plus a human-approved useful-speed threshold; beta adds concurrency, long-context, failure, and sustained-throughput thresholds.
Separate quantization/model-fit gains from runtime, transport, batching, and kernel gains.
Treat quants and 2–4/10+ stage counts only as named certification scenarios; no product logic may hardcode them.
Lock thresholds and stop conditions in versioned machine-readable data before benchmark result ingestion.
Applicable shared quality gates in prd.json pass, and the evidence handoff records exact commands/results, changed files, limitations, and dependency handoff.

Shared quality gates

Targeted deterministic tests pass; Python changes also pass python -m compileall packages tests.
git diff --check passes.
Default tests are model-download-free, API-credit-free, and GPU-free.
Evidence README records exact changed files, commands/results, limitations, and dependency handoff; no fabricated evidence or inherited completion credit.

Evidence handoff

Verified evidence: .scratch/distributed-gguf-runtime/evidence/DGR-019/README.md. Legacy evidence remains provenance only and grants no implementation completion credit.
